Sorry for the multiple posts...
But I just noticed that both names don't resolve in DNS:
The "www" name shows an IP, but the bare domain does not.
That will be a problem for HTTP-01 authentication.
If you can't get an IP for it...
You can just get a cert for the "www" name:
sudo certbot \
certonly \
--standalone \
--http-01-port 8080 \
-d www.thecampanileproject.org \
--dry-run
